Dear Dario,
I think differently, I think my examples show the resemblance between
the way of "dispatching" for S4 generic and that for C++ overloaded
function.
Both are dispatched ONLY through the type of arguments.
Again following your original example:
int larger(int x, int y);
char larger(char first, char second);
char larger(char x, char y){ # This will work!
if y>x y else x;
}
x = 'a' ; b='b';
larger(x,y); # this will still call the second function.
The declaration "char largerChar(char first, char second);" does not
make any constraint on the name of argument...
Hope this helps.
Best,
Lei Chen
